Oh boy, this one took some figuring out. The photo was just labelled ' Washington Place 1875 ', however, while maps from 1865 and 1880 showed there used to be Washington Street and Lane, there was no Place. I could tell by the geography it was near the wharves at Darling Harbour, with Pyrmont in the background. But I got a match for it with North Street. As you can see on the 1880 map below, both corner buildings on Sussex Street have angled doorways, then going down the lane there are six single storey huts on the left side, then four two-storey houses, with another single-storey building last ( map legend: the number in a circle = the number of storeys ) . At the end of the street is Biggs Foundry. These all match the photo, you can even just make out "Biggs" on the sign over the foundry entrance. And so today, the surrounding blocks were consolidated into one when Darling Harbour was redeveloped in the 1980s.
